I also have a spare rear wheel, with a 10 speed freehub however.
Ideally, I am thinking of fitting a new casette in my spare wheel along with a trainer specific tyre, so that I only swap the whole wheel depending on where I want to ride.
If I go for a 10 speed 11-25 casette, would I need to fiddle with the rear derailler every time?
Is it better to find a 11 speed rear wheel instead?

Thanks for any help
